From the screen capture that you have provided, it looks like the errors are coming from the client equipment connected to your 6500. You can perform some loopback test to isolate where the errors are coming from. You can apply a terminal software loopback on the 6500 client port and monitor the PM counts. If not errors are being detected, perform a facility loopback on the same 6500 client port and monitor the PM counts. The two tests mentioned will help you isolate where errors are coming from. Terminal loopback will isolate the client side and test the 6500 equipment back to the far-end ciricuit. While the facility loopback will isolate the 6500 equipment and you will be testing the circuit going back to your client equipment.
I hope this helps.
I am working with ciena 6500
Thank you Surender! I'm sharing this with our 6500 forum members should someone have experience and be able to help. I'll also monitor your question and reach out to some of our SMEs.
We have already tested according to steps mebmentio by you. As you suspected that it is from client side error and comming from customer, where it showing receiving error.
1)With terminal loop back no error.
2) facility loop back getting errors
Steps taken to resolve this issue.
1) checked connectivity between router and client side ( cleaned patch cords and SFP) still getting errors
2) changed SFP at router and changed patch cords between client side and router. Still getting errors.
3) self loop at both end ciena client side and router no errors at both ends.
4) resetted the client card still getting errors.
5) resetted line card errors cleared ( why and still looking for answers)
This type of issues are frequent now and getting cleared after cold reset the line card
Please help me to find the answer of this issue.
It looks like you have done a good job isolation the issue. Have you tried changing the Ciena client pluggable optics? I forgot to asked if you are only seeing the error from one side of the circuit. Step 3 shows that the errors are not coming from this side of the circuit and might be generated from the far-end. I would also suggest opening a ticket with Ciena technical support to help isolate where the errors are coming from. You can call the 1-800-CIENA24 (1-800-2436224) helpdesk for assistance.
The client side is having receive error at one end and transmit error at far end. I suspected that receiving error end is the problem end so perform troubleshooting steps however when no issue found so checked at transmitting end as well.
My question why errors are cleared after resetting the line board at side where errors being received. If the issue was at router end then errors shouldn't have cleared after line board and if issue was at client card then also should be cleared when cold resetted the client card.
2)If issue was at line card then why errors were received when facility loop was applied.
Issue cleared without changing any hardware at ciena end.
